5 | 529a8d17 | Iustin Pop | ----------------- |
6 | 529a8d17 | Iustin Pop | |
7 | 41c44dcf | Iustin Pop | *(Released Fri, 30 Jul 2010)* |
8 | 529a8d17 | Iustin Pop | |
9 | 529a8d17 | Iustin Pop | Important change: the internal RPC mechanism between Ganeti nodes has |
10 | 529a8d17 | Iustin Pop | changed from using a home-grown http library (based on the Python base |
11 | 529a8d17 | Iustin Pop | libraries) to use the PycURL library. This requires that PycURL is |
12 | 529a8d17 | Iustin Pop | installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked |
13 | 529a8d17 | Iustin Pop | against GnuTLS by default. cURL's support for GnuTLS had known issues |
14 | 529a8d17 | Iustin Pop | before cURL 7.21.0 and we recommend using the latest cURL release or |
15 | 529a8d17 | Iustin Pop | linking against OpenSSL. Most other distributions already link PycURL |
16 | 529a8d17 | Iustin Pop | and cURL against OpenSSL. The command:: |
17 | 529a8d17 | Iustin Pop | |
18 | 529a8d17 | Iustin Pop | python -c 'import pycurl; print pycurl.version' |
19 | 529a8d17 | Iustin Pop | |
20 | 529a8d17 | Iustin Pop | can be used to determine the libraries PycURL and cURL are linked |
21 | 529a8d17 | Iustin Pop | against. |
22 | 529a8d17 | Iustin Pop | |
23 | 529a8d17 | Iustin Pop | Other significant changes: |
24 | 529a8d17 | Iustin Pop | |
25 | 529a8d17 | Iustin Pop | - Rewrote much of the internals of the job queue, in order to achieve |
26 | 529a8d17 | Iustin Pop | better parallelism; this decouples job query operations from the job |
27 | 529a8d17 | Iustin Pop | processing, and it should allow much nicer behaviour of the master |
28 | 529a8d17 | Iustin Pop | daemon under load, and it also has uncovered some long-standing bugs |
29 | 529a8d17 | Iustin Pop | related to the job serialisation (now fixed) |
30 | 529a8d17 | Iustin Pop | - Added a default iallocator setting to the cluster parameters, |
31 | 529a8d17 | Iustin Pop | eliminating the need to always pass nodes or an iallocator for |
32 | 529a8d17 | Iustin Pop | operations that require selection of new node(s) |
33 | 529a8d17 | Iustin Pop | - Added experimental support for the LXC virtualization method |
34 | 529a8d17 | Iustin Pop | - Added support for OS parameters, which allows the installation of |
35 | 529a8d17 | Iustin Pop | instances to pass parameter to OS scripts in order to customise the |
36 | 529a8d17 | Iustin Pop | instance |
37 | 529a8d17 | Iustin Pop | - Added a hypervisor parameter controlling the migration type (live or |
38 | 529a8d17 | Iustin Pop | non-live), since hypervisors have various levels of reliability; this |
39 | 529a8d17 | Iustin Pop | has renamed the 'live' parameter to 'mode' |
40 | 529a8d17 | Iustin Pop | - Added a cluster parameter ``reserved_lvs`` that denotes reserved |
41 | 529a8d17 | Iustin Pop | logical volumes, meaning that cluster verify will ignore them and not |
42 | 529a8d17 | Iustin Pop | flag their presence as errors |
43 | 529a8d17 | Iustin Pop | - The watcher will now reset the error count for failed instances after |
44 | 529a8d17 | Iustin Pop | 8 hours, thus allowing self-healing if the problem that caused the |
45 | 529a8d17 | Iustin Pop | instances to be down/fail to start has cleared in the meantime |
46 | 529a8d17 | Iustin Pop | - Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti |
47 | 529a8d17 | Iustin Pop | check for, and warn, if the drbd module parameter ``usermode_helper`` |
48 | 529a8d17 | Iustin Pop | is not consistent with the cluster-wide setting; this is needed to |
49 | 529a8d17 | Iustin Pop | make diagnose easier of failed drbd creations |
50 | 529a8d17 | Iustin Pop | - Started adding base IPv6 support, but this is not yet |
51 | 529a8d17 | Iustin Pop | enabled/available for use |
52 | 529a8d17 | Iustin Pop | - Rename operations (cluster, instance) will now return the new name, |
53 | 529a8d17 | Iustin Pop | which is especially useful if a short name was passed in |
54 | 529a8d17 | Iustin Pop | - Added support for instance migration in RAPI |
55 | 529a8d17 | Iustin Pop | - Added a tool to pre-configure nodes for the SSH setup, before joining |
56 | 529a8d17 | Iustin Pop | them to the cluster; this will allow in the future a simplified model |
57 | 529a8d17 | Iustin Pop | for node joining (but not yet fully enabled in 2.2); this needs the |
58 | 529a8d17 | Iustin Pop | paramiko python library |
59 | 529a8d17 | Iustin Pop | - Fixed handling of name-resolving errors |
60 | 529a8d17 | Iustin Pop | - Fixed consistency of job results on the error path |
61 | 529a8d17 | Iustin Pop | - Fixed master-failover race condition when executed multiple times in |
62 | 529a8d17 | Iustin Pop | sequence |
63 | 529a8d17 | Iustin Pop | - Fixed many bugs related to the job queue (mostly introduced during the |
64 | 529a8d17 | Iustin Pop | 2.2 development cycle, so not all are impacting 2.1) |
65 | 529a8d17 | Iustin Pop | - Fixed instance migration with missing disk symlinks |
66 | 529a8d17 | Iustin Pop | - Fixed handling of unknown jobs in ``gnt-job archive`` |
67 | 529a8d17 | Iustin Pop | - And many other small fixes/improvements |
68 | 529a8d17 | Iustin Pop | |
69 | 529a8d17 | Iustin Pop | Internal changes: |
70 | 529a8d17 | Iustin Pop | |
71 | 529a8d17 | Iustin Pop | - Enhanced both the unittest and the QA coverage |
72 | 529a8d17 | Iustin Pop | - Switched the opcode validation to a generic model, and extended the |
73 | 529a8d17 | Iustin Pop | validation to all opcode parameters |
74 | 529a8d17 | Iustin Pop | - Changed more parts of the code that write shell scripts to use the |
75 | 529a8d17 | Iustin Pop | same class for this |
76 | 529a8d17 | Iustin Pop | - Switched the master daemon to use the asyncore library for the Luxi |
77 | 529a8d17 | Iustin Pop | server endpoint |
78 | 529a8d17 | Iustin Pop | |

82 | a0a470fa | Michael Hanselmann | |
83 | a0a470fa | Michael Hanselmann | *(Released Thu, 17 Jun 2010)* |
84 | ab221ddf | Michael Hanselmann | |
85 | e0897adf | Michael Hanselmann | - Added tool (``move-instance``) and infrastructure to move instances |
86 | e0897adf | Michael Hanselmann | between separate clusters (see :doc:`separate documentation |
87 | e0897adf | Michael Hanselmann | <move-instance>` and :doc:`design document <design-2.2>`) |
88 | e0897adf | Michael Hanselmann | - Added per-request RPC timeout |
89 | ab221ddf | Michael Hanselmann | - RAPI now requires a Content-Type header for requests with a body (e.g. |
90 | ab221ddf | Michael Hanselmann | ``PUT`` or ``POST``) which must be set to ``application/json`` (see |
91 | ab221ddf | Michael Hanselmann | RFC2616 (HTTP/1.1), section 7.2.1) |
92 | e0897adf | Michael Hanselmann | - ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not |
93 | e0897adf | Michael Hanselmann | reachable |
94 | e0897adf | Michael Hanselmann | - Implemented initial support for running Ganeti daemons as separate |
95 | e0897adf | Michael Hanselmann | users, see configure-time flags ``--with-user-prefix`` and |
96 | e0897adf | Michael Hanselmann | ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this |
97 | e0897adf | Michael Hanselmann | time) |
98 | e0897adf | Michael Hanselmann | - Instances can be removed after export (``gnt-backup export |
99 | e0897adf | Michael Hanselmann | --remove-instance``) |
100 | e0897adf | Michael Hanselmann | - Self-signed certificates generated by Ganeti now use a 2048 bit RSA |
101 | e0897adf | Michael Hanselmann | key (instead of 1024 bit) |
102 | e0897adf | Michael Hanselmann | - Added new cluster configuration file for cluster domain secret |
103 | e0897adf | Michael Hanselmann | - Import/export now use SSL instead of SSH |
104 | e0897adf | Michael Hanselmann | - Added support for showing estimated time when exporting an instance, |
105 | e0897adf | Michael Hanselmann | see the ``ganeti-os-interface(7)`` manpage and look for |
106 | e0897adf | Michael Hanselmann | ``EXP_SIZE_FD`` |

109 | ae828011 | Guido Trotter | Version 2.1.6 |
110 | ae828011 | Guido Trotter | ------------- |
111 | ae828011 | Guido Trotter | |
112 | ae828011 | Guido Trotter | *(Released Fri, 16 Jul 2010)* |
113 | ae828011 | Guido Trotter | |
114 | ae828011 | Guido Trotter | Bugfixes only: |
115 | ae828011 | Guido Trotter | - Add an option to only select some reboot types during qa/burnin. |
116 | ae828011 | Guido Trotter | (on some hypervisors consequent reboots are not supported) |
117 | ae828011 | Guido Trotter | - Fix infrequent race condition in master failover. Sometimes the old |
118 | ae828011 | Guido Trotter | master ip address would be still detected as up for a short time |
119 | ae828011 | Guido Trotter | after it was removed, causing failover to fail. |
120 | ae828011 | Guido Trotter | - Decrease mlockall warnings when the ctypes module is missing. On |
121 | ae828011 | Guido Trotter | Python 2.4 we support running even if no ctypes module is installed, |
122 | ae828011 | Guido Trotter | but we were too verbose about this issue. |
123 | ae828011 | Guido Trotter | - Fix building on old distributions, on which man doesn't have a |
124 | ae828011 | Guido Trotter | --warnings option. |
125 | ae828011 | Guido Trotter | - Fix RAPI not to ignore the MAC address on instance creation |
126 | ae828011 | Guido Trotter | - Implement the old instance creation format in the RAPI client. |

129 | 71cba20b | Guido Trotter | Version 2.1.5 |
130 | 71cba20b | Guido Trotter | ------------- |
131 | 71cba20b | Guido Trotter | |
132 | 1d4c743d | Guido Trotter | *(Released Thu, 01 Jul 2010)* |
133 | 71cba20b | Guido Trotter | |
134 | 71cba20b | Guido Trotter | A small bugfix release: |
135 | 71cba20b | Guido Trotter | - Fix disk adoption: broken by strict --disk option checking in 2.1.4 |
136 | 71cba20b | Guido Trotter | - Fix batch-create: broken in the whole 2.1 series due to a lookup on |
137 | 71cba20b | Guido Trotter | a non-existing option |
138 | 71cba20b | Guido Trotter | - Fix instance create: the --force-variant option was ignored |
139 | 1d4c743d | Guido Trotter | - Improve pylint 0.21 compatibility and warnings with Python 2.6 |
140 | 1d4c743d | Guido Trotter | - Fix modify node storage with non-FQDN arguments |
141 | 1d4c743d | Guido Trotter | - Fix RAPI client to authenticate under Python 2.6 when used |
142 | 1d4c743d | Guido Trotter | for more than 5 requests needing authentication |
143 | 1d4c743d | Guido Trotter | - Fix gnt-instance modify -t (storage) giving a wrong error message |
144 | 1d4c743d | Guido Trotter | when converting a non-shutdown drbd instance to plain |
145 | 71cba20b | Guido Trotter | |

147 | c1a25b88 | Guido Trotter | Version 2.1.4 |
148 | c1a25b88 | Guido Trotter | ------------- |
149 | c1a25b88 | Guido Trotter | |
150 | 3ef56ab6 | Guido Trotter | *(Released Fri, 18 Jun 2010)* |
151 | c1a25b88 | Guido Trotter | |
152 | c1a25b88 | Guido Trotter | A small bugfix release: |
153 | c1a25b88 | Guido Trotter | |
154 | c1a25b88 | Guido Trotter | - Fix live migration of KVM instances started with older Ganeti |
155 | c1a25b88 | Guido Trotter | versions which had fewer hypervisor parameters |
156 | c1a25b88 | Guido Trotter | - Fix gnt-instance grow-disk on down instances |
157 | c1a25b88 | Guido Trotter | - Fix an error-reporting bug during instance migration |
158 | c1a25b88 | Guido Trotter | - Better checking of the ``--net`` and ``--disk`` values, to avoid |
159 | c1a25b88 | Guido Trotter | silently ignoring broken ones |
160 | c1a25b88 | Guido Trotter | - Fix an RPC error reporting bug affecting, for example, RAPI client |
161 | c1a25b88 | Guido Trotter | users |
162 | c1a25b88 | Guido Trotter | - Fix bug triggered by different API version os-es on different nodes |
163 | c1a25b88 | Guido Trotter | - Fix a bug in instance startup with custom hvparams: OS level |
164 | c1a25b88 | Guido Trotter | parameters would fail to be applied. |
165 | 3ef56ab6 | Guido Trotter | - Fix the RAPI client under Python 2.6 (but more work is needed to |
166 | 3ef56ab6 | Guido Trotter | make it work completely well with OpenSSL) |
167 | 3ef56ab6 | Guido Trotter | - Fix handling of errors when resolving names from DNS |
168 | c1a25b88 | Guido Trotter | |

170 | 14d91053 | Guido Trotter | Version 2.1.3 |
171 | 14d91053 | Guido Trotter | ------------- |
172 | 14d91053 | Guido Trotter | |
173 | 7cf722ea | Guido Trotter | *(Released Thu, 3 Jun 2010)* |
174 | 14d91053 | Guido Trotter | |
175 | 14d91053 | Guido Trotter | A medium sized development cycle. Some new features, and some |
176 | 14d91053 | Guido Trotter | fixes/small improvements/cleanups. |
177 | 14d91053 | Guido Trotter | |
178 | 14d91053 | Guido Trotter | Significant features |
179 | 14d91053 | Guido Trotter | ~~~~~~~~~~~~~~~~~~~~ |
180 | 14d91053 | Guido Trotter | |
181 | 14d91053 | Guido Trotter | The node deamon now tries to mlock itself into memory, unless the |
182 | 14d91053 | Guido Trotter | ``--no-mlock`` flag is passed. It also doesn't fail if it can't write |
183 | 14d91053 | Guido Trotter | its logs, and falls back to console logging. This allows emergency |
184 | 14d91053 | Guido Trotter | features such as ``gnt-node powercycle`` to work even in the event of a |
185 | 14d91053 | Guido Trotter | broken node disk (tested offlining the disk hosting the node's |
186 | 722702e3 | Guido Trotter | filesystem and dropping its memory caches; don't try this at home) |
187 | 14d91053 | Guido Trotter | |
188 | 14d91053 | Guido Trotter | KVM: add vhost-net acceleration support. It can be tested with a new |
189 | 14d91053 | Guido Trotter | enough version of the kernel and of qemu-kvm. |
190 | 14d91053 | Guido Trotter | |
191 | 14d91053 | Guido Trotter | KVM: Add instance chrooting feature. If you use privilege dropping for |
192 | 14d91053 | Guido Trotter | your VMs you can also now force them to chroot to an empty directory, |
193 | 14d91053 | Guido Trotter | before starting the emulated guest. |
194 | 14d91053 | Guido Trotter | |
195 | 14d91053 | Guido Trotter | KVM: Add maximum migration bandwith and maximum downtime tweaking |
196 | 14d91053 | Guido Trotter | support (requires a new-enough version of qemu-kvm). |
197 | 14d91053 | Guido Trotter | |
198 | 14d91053 | Guido Trotter | Cluster verify will now warn if the master node doesn't have the master |
199 | 14d91053 | Guido Trotter | ip configured on it. |
200 | 14d91053 | Guido Trotter | |
201 | 14d91053 | Guido Trotter | Add a new (incompatible) instance creation request format to RAPI which |
202 | 14d91053 | Guido Trotter | supports all parameters (previously only a subset was supported, and it |
203 | 14d91053 | Guido Trotter | wasn't possible to extend the old format to accomodate all the new |
204 | 14d91053 | Guido Trotter | features. The old format is still supported, and a client can check for |
205 | 14d91053 | Guido Trotter | this feature, before using it, by checking for its presence in the |
206 | 14d91053 | Guido Trotter | ``features`` RAPI resource. |
207 | 14d91053 | Guido Trotter | |
208 | 14d91053 | Guido Trotter | Now with ancient latin support. Try it passing the ``--roman`` option to |
209 | 722702e3 | Guido Trotter | ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list`` |
210 | 722702e3 | Guido Trotter | (requires the python-roman module to be installed, in order to work). |
211 | 14d91053 | Guido Trotter | |
212 | 14d91053 | Guido Trotter | Other changes |
213 | 14d91053 | Guido Trotter | ~~~~~~~~~~~~~ |
214 | 14d91053 | Guido Trotter | |
215 | 14d91053 | Guido Trotter | As usual many internal code refactorings, documentation updates, and |
216 | 14d91053 | Guido Trotter | such. Among others: |
217 | 14d91053 | Guido Trotter | |
218 | 14d91053 | Guido Trotter | - Lots of improvements and cleanups to the experimental Remote API |
219 | 14d91053 | Guido Trotter | (RAPI) client library. |
220 | 14d91053 | Guido Trotter | - A new unit test suite for the core daemon libraries. |
221 | 14d91053 | Guido Trotter | - A fix to creating missing directories makes sure the umask is not |
222 | 14d91053 | Guido Trotter | applied anymore. This enforces the same directory permissions |
223 | 14d91053 | Guido Trotter | everywhere. |
224 | 14d91053 | Guido Trotter | - Better handling terminating daemons with ctrl+c (used when running |
225 | 14d91053 | Guido Trotter | them in debugging mode). |
226 | 14d91053 | Guido Trotter | - Fix a race condition in live migrating a KVM instance, when stat() |
227 | 14d91053 | Guido Trotter | on the old proc status file returned EINVAL, which is an unexpected |
228 | 14d91053 | Guido Trotter | value. |
229 | 1de45c78 | Guido Trotter | - Fixed manpage checking with newer man and utf-8 charachters. But now |
230 | 1de45c78 | Guido Trotter | you need the en_US.UTF-8 locale enabled to build Ganeti from git. |
231 | 14d91053 | Guido Trotter | |
232 | 14d91053 | Guido Trotter | |
233 | 23f983f4 | Guido Trotter | Version 2.1.2.1 |
234 | 23f983f4 | Guido Trotter | --------------- |
235 | 23f983f4 | Guido Trotter | |
236 | 23f983f4 | Guido Trotter | *(Released Fri, 7 May 2010)* |
237 | 23f983f4 | Guido Trotter | |
238 | 23f983f4 | Guido Trotter | Fix a bug which prevented untagged KVM instances from starting. |
239 | 23f983f4 | Guido Trotter | |
240 | 507fd05a | Guido Trotter | |
241 | ba538816 | Iustin Pop | Version 2.1.2 |
242 | ba538816 | Iustin Pop | ------------- |
243 | ba538816 | Iustin Pop | |
244 | ace6cbe8 | Iustin Pop | *(Released Fri, 7 May 2010)* |
245 | ba538816 | Iustin Pop | |
246 | ba538816 | Iustin Pop | Another release with a long development cycle, during which many |
247 | ba538816 | Iustin Pop | different features were added. |
248 | ba538816 | Iustin Pop | |
249 | ba538816 | Iustin Pop | Significant features |
250 | ba538816 | Iustin Pop | ~~~~~~~~~~~~~~~~~~~~ |
251 | ba538816 | Iustin Pop | |
252 | ba538816 | Iustin Pop | The KVM hypervisor now can run the individual instances as non-root, to |
253 | ba538816 | Iustin Pop | reduce the impact of a VM being hijacked due to bugs in the |
254 | ba538816 | Iustin Pop | hypervisor. It is possible to run all instances as a single (non-root) |
255 | ba538816 | Iustin Pop | user, to manually specify a user for each instance, or to dynamically |
256 | ba538816 | Iustin Pop | allocate a user out of a cluster-wide pool to each instance, with the |
257 | ba538816 | Iustin Pop | guarantee that no two instances will run under the same user ID on any |
258 | ba538816 | Iustin Pop | given node. |
259 | ba538816 | Iustin Pop | |
260 | ba538816 | Iustin Pop | An experimental RAPI client library, that can be used standalone |
261 | ba538816 | Iustin Pop | (without the other Ganeti libraries), is provided in the source tree as |
262 | ba538816 | Iustin Pop | ``lib/rapi/client.py``. Note this client might change its interface in |
263 | ba538816 | Iustin Pop | the future, as we iterate on its capabilities. |
264 | ba538816 | Iustin Pop | |
265 | ba538816 | Iustin Pop | A new command, ``gnt-cluster renew-crypto`` has been added to easily |
266 | ba538816 | Iustin Pop | replace the cluster's certificates and crypto keys. This might help in |
267 | ba538816 | Iustin Pop | case they have been compromised, or have simply expired. |
268 | ba538816 | Iustin Pop | |
269 | ba538816 | Iustin Pop | A new disk option for instance creation has been added that allows one |
270 | ba538816 | Iustin Pop | to "adopt" currently existing logical volumes, with data |
271 | ba538816 | Iustin Pop | preservation. This should allow easier migration to Ganeti from |
272 | ba538816 | Iustin Pop | unmanaged (or managed via other software) instances. |
273 | ba538816 | Iustin Pop | |
274 | ba538816 | Iustin Pop | Another disk improvement is the possibility to convert between redundant |
275 | ba538816 | Iustin Pop | (DRBD) and plain (LVM) disk configuration for an instance. This should |
276 | ba538816 | Iustin Pop | allow better scalability (starting with one node and growing the |
277 | ba538816 | Iustin Pop | cluster, or shrinking a two-node cluster to one node). |
278 | ba538816 | Iustin Pop | |
279 | ba538816 | Iustin Pop | A new feature that could help with automated node failovers has been |
280 | ba538816 | Iustin Pop | implemented: if a node sees itself as offline (by querying the master |
281 | ba538816 | Iustin Pop | candidates), it will try to shutdown (hard) all instances and any active |
282 | ba538816 | Iustin Pop | DRBD devices. This reduces the risk of duplicate instances if an |
283 | ba538816 | Iustin Pop | external script automatically failovers the instances on such nodes. To |
284 | ba538816 | Iustin Pop | enable this, the cluster parameter ``maintain_node_health`` should be |
285 | ba538816 | Iustin Pop | enabled; in the future this option (per the name) will enable other |
286 | ba538816 | Iustin Pop | automatic maintenance features. |
287 | ba538816 | Iustin Pop | |
288 | ba538816 | Iustin Pop | Instance export/import now will reuse the original instance |
289 | ba538816 | Iustin Pop | specifications for all parameters; that means exporting an instance, |
290 | ba538816 | Iustin Pop | deleting it and the importing it back should give an almost identical |
291 | ba538816 | Iustin Pop | instance. Note that the default import behaviour has changed from |
292 | ba538816 | Iustin Pop | before, where it created only one NIC; now it recreates the original |
293 | ba538816 | Iustin Pop | number of NICs. |
294 | ba538816 | Iustin Pop | |
295 | ba538816 | Iustin Pop | Cluster verify has added a few new checks: SSL certificates validity, |
296 | ba538816 | Iustin Pop | /etc/hosts consistency across the cluster, etc. |
297 | ba538816 | Iustin Pop | |
298 | ba538816 | Iustin Pop | Other changes |
299 | ba538816 | Iustin Pop | ~~~~~~~~~~~~~ |
300 | ba538816 | Iustin Pop | |
301 | ba538816 | Iustin Pop | As usual, many internal changes were done, documentation fixes, |
302 | ba538816 | Iustin Pop | etc. Among others: |
303 | ba538816 | Iustin Pop | |
304 | ba538816 | Iustin Pop | - Fixed cluster initialization with disabled cluster storage (regression |
305 | ba538816 | Iustin Pop | introduced in 2.1.1) |
306 | ba538816 | Iustin Pop | - File-based storage supports growing the disks |
307 | ba538816 | Iustin Pop | - Fixed behaviour of node role changes |
308 | ba538816 | Iustin Pop | - Fixed cluster verify for some corner cases, plus a general rewrite of |
309 | ba538816 | Iustin Pop | cluster verify to allow future extension with more checks |
310 | ba538816 | Iustin Pop | - Fixed log spamming by watcher and node daemon (regression introduced |
311 | ba538816 | Iustin Pop | in 2.1.1) |
312 | ba538816 | Iustin Pop | - Fixed possible validation issues when changing the list of enabled |
313 | ba538816 | Iustin Pop | hypervisors |
314 | ba538816 | Iustin Pop | - Fixed cleanup of /etc/hosts during node removal |
315 | ba538816 | Iustin Pop | - Fixed RAPI response for invalid methods |
316 | ba538816 | Iustin Pop | - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon |
317 | ba538816 | Iustin Pop | - Multiple small improvements to the KVM hypervisor (VNC usage, booting |
318 | ba538816 | Iustin Pop | from ide disks, etc.) |
319 | ba538816 | Iustin Pop | - Allow OS changes without re-installation (to record a changed OS |
320 | ba538816 | Iustin Pop | outside of Ganeti, or to allow OS renames) |
321 | ba538816 | Iustin Pop | - Allow instance creation without OS installation (useful for example if |
322 | ba538816 | Iustin Pop | the OS will be installed manually, or restored from a backup not in |
323 | ba538816 | Iustin Pop | Ganeti format) |
324 | ba538816 | Iustin Pop | - Implemented option to make cluster ``copyfile`` use the replication |
325 | ba538816 | Iustin Pop | network |
326 | ba538816 | Iustin Pop | - Added list of enabled hypervisors to ssconf (possibly useful for |
327 | ba538816 | Iustin Pop | external scripts) |
328 | ba538816 | Iustin Pop | - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from |
329 | ba538816 | Iustin Pop | 1.2 clusters |
330 | ba538816 | Iustin Pop | - A partial form of node re-IP is possible via node readd, which now |
331 | ba538816 | Iustin Pop | allows changed node primary IP |
332 | ba538816 | Iustin Pop | - Command line utilities now show an informational message if the job is |
333 | ba538816 | Iustin Pop | waiting for a lock |
334 | ba538816 | Iustin Pop | - The logs of the master daemon now show the PID/UID/GID of the |
335 | ba538816 | Iustin Pop | connected client |
336 | ba538816 | Iustin Pop | |
337 | ba538816 | Iustin Pop | |
338 | c655522d | Iustin Pop | Version 2.1.1 |
339 | c655522d | Iustin Pop | ------------- |
340 | c655522d | Iustin Pop | |
341 | bdc93557 | Iustin Pop | *(Released Fri, 12 Mar 2010)* |
342 | bdc93557 | Iustin Pop | |
343 | c655522d | Iustin Pop | During the 2.1.0 long release candidate cycle, a lot of improvements and |
344 | c655522d | Iustin Pop | changes have accumulated with were released later as 2.1.1. |
345 | c655522d | Iustin Pop | |
346 | c655522d | Iustin Pop | Major changes |
347 | c655522d | Iustin Pop | ~~~~~~~~~~~~~ |
348 | c655522d | Iustin Pop | |
349 | c655522d | Iustin Pop | The node evacuate command (``gnt-node evacuate``) was significantly |
350 | c655522d | Iustin Pop | rewritten, and as such the IAllocator protocol was changed - a new |
351 | c655522d | Iustin Pop | request type has been added. This unfortunate change during a stable |
352 | c655522d | Iustin Pop | series is designed to improve performance of node evacuations; on |
353 | c655522d | Iustin Pop | clusters with more than about five nodes and which are well-balanced, |
354 | c655522d | Iustin Pop | evacuation should proceed in parallel for all instances of the node |
355 | c655522d | Iustin Pop | being evacuated. As such, any existing IAllocator scripts need to be |
356 | c655522d | Iustin Pop | updated, otherwise the above command will fail due to the unknown |
357 | c655522d | Iustin Pop | request. The provided "dumb" allocator has not been updated; but the |
358 | c655522d | Iustin Pop | ganeti-htools package supports the new protocol since version 0.2.4. |
359 | c655522d | Iustin Pop | |
360 | c655522d | Iustin Pop | Another important change is increased validation of node and instance |
361 | c655522d | Iustin Pop | names. This might create problems in special cases, if invalid host |
362 | c655522d | Iustin Pop | names are being used. |
363 | c655522d | Iustin Pop | |
364 | c655522d | Iustin Pop | Also, a new layer of hypervisor parameters has been added, that sits at |
365 | c655522d | Iustin Pop | OS level between the cluster defaults and the instance ones. This allows |
366 | c655522d | Iustin Pop | customisation of virtualization parameters depending on the installed |
367 | c655522d | Iustin Pop | OS. For example instances with OS 'X' may have a different KVM kernel |
368 | c655522d | Iustin Pop | (or any other parameter) than the cluster defaults. This is intended to |
369 | c655522d | Iustin Pop | help managing a multiple OSes on the same cluster, without manual |
370 | c655522d | Iustin Pop | modification of each instance's parameters. |
371 | c655522d | Iustin Pop | |
372 | c655522d | Iustin Pop | A tool for merging clusters, ``cluster-merge``, has been added in the |
373 | c655522d | Iustin Pop | tools sub-directory. |
374 | c655522d | Iustin Pop | |
375 | c655522d | Iustin Pop | Bug fixes |
376 | c655522d | Iustin Pop | ~~~~~~~~~ |
377 | c655522d | Iustin Pop | |
378 | c655522d | Iustin Pop | - Improved the int/float conversions that should make the code more |
379 | c655522d | Iustin Pop | robust in face of errors from the node daemons |
380 | c655522d | Iustin Pop | - Fixed the remove node code in case of internal configuration errors |
381 | c655522d | Iustin Pop | - Fixed the node daemon behaviour in face of inconsistent queue |
382 | c655522d | Iustin Pop | directory (e.g. read-only file-system where we can't open the files |
383 | c655522d | Iustin Pop | read-write, etc.) |
384 | c655522d | Iustin Pop | - Fixed the behaviour of gnt-node modify for master candidate demotion; |
385 | c655522d | Iustin Pop | now it either aborts cleanly or, if given the new โauto_promoteโ |
386 | c655522d | Iustin Pop | parameter, will automatically promote other nodes as needed |
387 | c655522d | Iustin Pop | - Fixed compatibility with (unreleased yet) Python 2.6.5 that would |
388 | c655522d | Iustin Pop | completely prevent Ganeti from working |
389 | c655522d | Iustin Pop | - Fixed bug for instance export when not all disks were successfully |
390 | c655522d | Iustin Pop | exported |
391 | c655522d | Iustin Pop | - Fixed behaviour of node add when the new node is slow in starting up |
392 | c655522d | Iustin Pop | the node daemon |
393 | c655522d | Iustin Pop | - Fixed handling of signals in the LUXI client, which should improve |
394 | c655522d | Iustin Pop | behaviour of command-line scripts |
395 | c655522d | Iustin Pop | - Added checks for invalid node/instance names in the configuration (now |
396 | c655522d | Iustin Pop | flagged during cluster verify) |
397 | c655522d | Iustin Pop | - Fixed watcher behaviour for disk activation errors |
398 | c655522d | Iustin Pop | - Fixed two potentially endless loops in http library, which led to the |
399 | c655522d | Iustin Pop | RAPI daemon hanging and consuming 100% CPU in some cases |
400 | c655522d | Iustin Pop | - Fixed bug in RAPI daemon related to hashed passwords |
401 | c655522d | Iustin Pop | - Fixed bug for unintended qemu-level bridging of multi-NIC KVM |
402 | c655522d | Iustin Pop | instances |
403 | c655522d | Iustin Pop | - Enhanced compatibility with non-Debian OSes, but not using absolute |
404 | c655522d | Iustin Pop | path in some commands and allowing customisation of the ssh |
405 | c655522d | Iustin Pop | configuration directory |
406 | c655522d | Iustin Pop | - Fixed possible future issue with new Python versions by abiding to the |
407 | c655522d | Iustin Pop | proper use of ``__slots__`` attribute on classes |
408 | c655522d | Iustin Pop | - Added checks that should prevent directory traversal attacks |
409 | c655522d | Iustin Pop | - Many documentation fixes based on feedback from users |
410 | c655522d | Iustin Pop | |
411 | c655522d | Iustin Pop | New features |
412 | c655522d | Iustin Pop | ~~~~~~~~~~~~ |
413 | c655522d | Iustin Pop | |
414 | c655522d | Iustin Pop | - Added an โearly_releaseโ more for instance replace disks and node |
415 | c655522d | Iustin Pop | evacuate, where we release locks earlier and thus allow higher |
416 | c655522d | Iustin Pop | parallelism within the cluster |
417 | c655522d | Iustin Pop | - Added watcher hooks, intended to allow the watcher to restart other |
418 | c655522d | Iustin Pop | daemons (e.g. from the ganeti-nbma project), but they can be used of |
419 | c655522d | Iustin Pop | course for any other purpose |
420 | c655522d | Iustin Pop | - Added a compile-time disable for DRBD barriers, to increase |
421 | c655522d | Iustin Pop | performance if the administrator trusts the power supply or the |
422 | c655522d | Iustin Pop | storage system to not lose writes |
423 | c655522d | Iustin Pop | - Added the option of using syslog for logging instead of, or in |
424 | c655522d | Iustin Pop | addition to, Ganeti's own log files |
425 | c655522d | Iustin Pop | - Removed boot restriction for paravirtual NICs for KVM, recent versions |
426 | c655522d | Iustin Pop | can indeed boot from a paravirtual NIC |
427 | c655522d | Iustin Pop | - Added a generic debug level for many operations; while this is not |
428 | c655522d | Iustin Pop | used widely yet, it allows one to pass the debug value all the way to |
429 | c655522d | Iustin Pop | the OS scripts |
430 | c655522d | Iustin Pop | - Enhanced the hooks environment for instance moves (failovers, |
431 | c655522d | Iustin Pop | migrations) where the primary/secondary nodes changed during the |
432 | c655522d | Iustin Pop | operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars |
433 | c655522d | Iustin Pop | - Enhanced data validations for many user-supplied values; one important |
434 | c655522d | Iustin Pop | item is the restrictions imposed on instance and node names, which |
435 | c655522d | Iustin Pop | might reject some (invalid) host names |
436 | c655522d | Iustin Pop | - Add a configure-time option to disable file-based storage, if it's not |
437 | c655522d | Iustin Pop | needed; this allows greater security separation between the master |
438 | c655522d | Iustin Pop | node and the other nodes from the point of view of the inter-node RPC |
439 | c655522d | Iustin Pop | protocol |
440 | c655522d | Iustin Pop | - Added user notification in interactive tools if job is waiting in the |
441 | c655522d | Iustin Pop | job queue or trying to acquire locks |
442 | c655522d | Iustin Pop | - Added log messages when a job is waiting for locks |
443 | c655522d | Iustin Pop | - Added filtering by node tags in instance operations which admit |
444 | c655522d | Iustin Pop | multiple instances (start, stop, reboot, reinstall) |
445 | c655522d | Iustin Pop | - Added a new tool for cluster mergers, ``cluster-merge`` |
446 | c655522d | Iustin Pop | - Parameters from command line which are of the form ``a=b,c=d`` can now |
447 | c655522d | Iustin Pop | use backslash escapes to pass in values which contain commas, |
448 | c655522d | Iustin Pop | e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value |
449 | c655522d | Iustin Pop | ``b,c`` |
450 | c655522d | Iustin Pop | - For KVM, the instance name is the first parameter passed to KVM, so |
451 | c655522d | Iustin Pop | that it's more visible in the process list |
452 | c655522d | Iustin Pop | |
453 | c655522d | Iustin Pop | |

462 | 920a91bf | Michael Hanselmann | - Added new daemon to export configuration data in a cheaper way than |
463 | 920a91bf | Michael Hanselmann | using the remote API |
464 | 920a91bf | Michael Hanselmann | - Instance NICs can now be routed instead of being associated with a |
465 | 920a91bf | Michael Hanselmann | networking bridge |
466 | 920a91bf | Michael Hanselmann | - Improved job locking logic to reduce impact of jobs acquiring multiple |
467 | 920a91bf | Michael Hanselmann | locks waiting for other long-running jobs |
468 | 920a91bf | Michael Hanselmann | |
469 | bfe61b0b | Iustin Pop | In-depth implementation details can be found in the Ganeti 2.1 design |

504 | 920a91bf | Michael Hanselmann | (``ssconf_node_primary_ips``) and node secondary IP address |
505 | 920a91bf | Michael Hanselmann | (``ssconf_node_secondary_ips``) |
506 | 920a91bf | Michael Hanselmann | - Added ``ganeti-confd`` and a client library to query the Ganeti |
507 | 920a91bf | Michael Hanselmann | configuration via UDP |
508 | 920a91bf | Michael Hanselmann | - Added ability to run hooks after cluster initialization and before |
509 | 920a91bf | Michael Hanselmann | cluster destruction |

523 | cc291012 | Iustin Pop | - Added UUIDs to the main config entities (cluster, nodes, instances) |
524 | 920a91bf | Michael Hanselmann | - Added support for OS variants |
525 | 936f3c59 | Michael Hanselmann | - Added support for hashed passwords in the Ganeti remote API users file |

624 | 61b5e342 | Michael Hanselmann | |
625 | bdc93557 | Iustin Pop | *(Released Fri, 7 Aug 2009)* |
626 | bdc93557 | Iustin Pop | |
627 | 61b5e342 | Michael Hanselmann | - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command |
628 | 61b5e342 | Michael Hanselmann | to allow using the pre-2.0.2 behaviour in activation, if any existing |
629 | 61b5e342 | Michael Hanselmann | instances have mismatched disk sizes in the configuration |
630 | 7faf5110 | Michael Hanselmann | - Added ``gnt-cluster repair-disk-sizes`` command to check and update |
631 | 7faf5110 | Michael Hanselmann | any configuration mismatches for disk sizes |
632 | 61b5e342 | Michael Hanselmann | - Added ``gnt-master cluste-failover --no-voting`` to allow master |

637 | 61b5e342 | Michael Hanselmann | - Fixed exit code of ``gnt-backup export`` |
638 | 61b5e342 | Michael Hanselmann | |

642 | 61b5e342 | Michael Hanselmann | |
643 | bdc93557 | Iustin Pop | *(Released Fri, 17 Jul 2009)* |
644 | bdc93557 | Iustin Pop | |
645 | 61b5e342 | Michael Hanselmann | - Added experimental support for stripped logical volumes; this should |
646 | 61b5e342 | Michael Hanselmann | enhance performance but comes with a higher complexity in the block |
647 | 61b5e342 | Michael Hanselmann | device handling; stripping is only enabled when passing |
648 | 61b5e342 | Michael Hanselmann | ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are |
649 | 61b5e342 | Michael Hanselmann | affected even in the non-stripped mode |
650 | 61b5e342 | Michael Hanselmann | - Improved resiliency against transient failures at the end of DRBD |
651 | 61b5e342 | Michael Hanselmann | resyncs, and in general of DRBD resync checks |
652 | 61b5e342 | Michael Hanselmann | - Fixed a couple of issues with exports and snapshot errors |
653 | 61b5e342 | Michael Hanselmann | - Fixed a couple of issues in instance listing |
654 | 61b5e342 | Michael Hanselmann | - Added display of the disk size in ``gnt-instance info`` |
655 | 61b5e342 | Michael Hanselmann | - Fixed checking for valid OSes in instance creation |
656 | aa287e8c | Michael Hanselmann | - Fixed handling of the "vcpus" parameter in instance listing and in |
657 | 61b5e342 | Michael Hanselmann | general of invalid parameters |
658 | 61b5e342 | Michael Hanselmann | - Fixed http server library, and thus RAPI, to handle invalid |
659 | 61b5e342 | Michael Hanselmann | username/password combinations correctly; this means that now they |
660 | 61b5e342 | Michael Hanselmann | report unauthorized for queries too, not only for modifications, |
661 | 61b5e342 | Michael Hanselmann | allowing earlier detect of configuration problems |
662 | aa287e8c | Michael Hanselmann | - Added a new "role" node list field, equivalent to the master/master |
663 | 61b5e342 | Michael Hanselmann | candidate/drained/offline flags combinations |
664 | 61b5e342 | Michael Hanselmann | - Fixed cluster modify and changes of candidate pool size |
665 | 61b5e342 | Michael Hanselmann | - Fixed cluster verify error messages for wrong files on regular nodes |
666 | 61b5e342 | Michael Hanselmann | - Fixed a couple of issues with node demotion from master candidate role |
667 | 61b5e342 | Michael Hanselmann | - Fixed node readd issues |
668 | 61b5e342 | Michael Hanselmann | - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup |
669 | aa287e8c | Michael Hanselmann | - Added a new ``--no-voting`` option for masterfailover to fix failover |
670 | aa287e8c | Michael Hanselmann | on two-nodes clusters when the former master node is unreachable |
671 | 61b5e342 | Michael Hanselmann | - Added instance reinstall over RAPI |

675 | 61b5e342 | Michael Hanselmann | ------------- |
676 | 61b5e342 | Michael Hanselmann | |
677 | bdc93557 | Iustin Pop | *(Released Tue, 16 Jun 2009)* |
678 | bdc93557 | Iustin Pop | |
679 | 61b5e342 | Michael Hanselmann | - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will |
680 | 61b5e342 | Michael Hanselmann | allow re-adding the start in single-user option (regression from 1.2) |
681 | 61b5e342 | Michael Hanselmann | - the watcher writes the instance status to a file, to allow monitoring |
682 | 61b5e342 | Michael Hanselmann | to report the instance status (from the master) based on cached |
683 | 61b5e342 | Michael Hanselmann | results of the watcher's queries; while this can get stale if the |
684 | 61b5e342 | Michael Hanselmann | watcher is being locked due to other work on the cluster, this is |
685 | 61b5e342 | Michael Hanselmann | still an improvement |
686 | 61b5e342 | Michael Hanselmann | - the watcher now also restarts the node daemon and the rapi daemon if |
687 | 61b5e342 | Michael Hanselmann | they died |
688 | 61b5e342 | Michael Hanselmann | - fixed the watcher to handle full and drained queue cases |
689 | 7faf5110 | Michael Hanselmann | - hooks export more instance data in the environment, which helps if |
690 | 7faf5110 | Michael Hanselmann | hook scripts need to take action based on the instance's properties |
691 | 7faf5110 | Michael Hanselmann | (no longer need to query back into ganeti) |
692 | 61b5e342 | Michael Hanselmann | - instance failovers when the instance is stopped do not check for free |
693 | 61b5e342 | Michael Hanselmann | RAM, so that failing over a stopped instance is possible in low memory |
694 | 61b5e342 | Michael Hanselmann | situations |
695 | 61b5e342 | Michael Hanselmann | - rapi uses queries for tags instead of jobs (for less job traffic), and |
696 | 61b5e342 | Michael Hanselmann | for cluster tags it won't talk to masterd at all but read them from |
697 | 61b5e342 | Michael Hanselmann | ssconf |
698 | 61b5e342 | Michael Hanselmann | - a couple of error handling fixes in RAPI |
699 | 61b5e342 | Michael Hanselmann | - drbd handling: improved the error handling of inconsistent disks after |
700 | 61b5e342 | Michael Hanselmann | resync to reduce the frequency of "there are some degraded disks for |
701 | 61b5e342 | Michael Hanselmann | this instance" messages |
702 | 61b5e342 | Michael Hanselmann | - fixed a bug in live migration when DRBD doesn't want to reconnect (the |
703 | 61b5e342 | Michael Hanselmann | error handling path called a wrong function name) |

730 | 61b5e342 | Michael Hanselmann | - change the OS list to not require locks; this helps with big clusters |
731 | 61b5e342 | Michael Hanselmann | - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the |
732 | 61b5e342 | Michael Hanselmann | volume group is broken |
733 | 61b5e342 | Michael Hanselmann | - ``gnt-instance info``, without any arguments, doesn't run for all |
734 | 61b5e342 | Michael Hanselmann | instances anymore; either pass ``--all`` or pass the desired |
735 | 61b5e342 | Michael Hanselmann | instances; this helps against mistakes on big clusters where listing |
736 | 61b5e342 | Michael Hanselmann | the information for all instances takes a long time |

785 | bdc93557 | Iustin Pop | |
786 | 61b5e342 | Michael Hanselmann | - Xen PVM and KVM have switched the default value for the instance root |
787 | 61b5e342 | Michael Hanselmann | disk to the first partition on the first drive, instead of the whole |
788 | 61b5e342 | Michael Hanselmann | drive; this means that the OS installation scripts must be changed |
789 | 61b5e342 | Michael Hanselmann | accordingly |
790 | 61b5e342 | Michael Hanselmann | - Man pages have been updated |
791 | 61b5e342 | Michael Hanselmann | - RAPI has been switched by default to HTTPS, and the exported functions |

804 | 61b5e342 | Michael Hanselmann | - Version 2 is a general rewrite of the code and therefore the |
805 | 61b5e342 | Michael Hanselmann | differences are too many to list, see the design document for 2.0 in |
806 | 61b5e342 | Michael Hanselmann | the ``doc/`` subdirectory for more details |
807 | 61b5e342 | Michael Hanselmann | - In this beta version there is not yet a migration path from 1.2 (there |

809 | 61b5e342 | Michael Hanselmann | - A few significant changes are: |
810 | 61b5e342 | Michael Hanselmann | |
811 | 61b5e342 | Michael Hanselmann | - all commands are executed by a daemon (``ganeti-masterd``) and the |
812 | 61b5e342 | Michael Hanselmann | various ``gnt-*`` commands are just front-ends to it |
813 | 7faf5110 | Michael Hanselmann | - all the commands are entered into, and executed from a job queue, |
814 | 7faf5110 | Michael Hanselmann | see the ``gnt-job(8)`` manpage |
815 | 7faf5110 | Michael Hanselmann | - the RAPI daemon supports read-write operations, secured by basic |
816 | 7faf5110 | Michael Hanselmann | HTTP authentication on top of HTTPS |
817 | 61b5e342 | Michael Hanselmann | - DRBD version 0.7 support has been removed, DRBD 8 is the only |
818 | 61b5e342 | Michael Hanselmann | supported version (when migrating from Ganeti 1.2 to 2.0, you need |
819 | 61b5e342 | Michael Hanselmann | to migrate to DRBD 8 first while still running Ganeti 1.2) |
820 | 61b5e342 | Michael Hanselmann | - DRBD devices are using statically allocated minor numbers, which |
821 | 61b5e342 | Michael Hanselmann | will be assigned to existing instances during the migration process |
822 | 61b5e342 | Michael Hanselmann | - there is support for both Xen PVM and Xen HVM instances running on |
823 | 61b5e342 | Michael Hanselmann | the same cluster |
824 | 61b5e342 | Michael Hanselmann | - KVM virtualization is supported too |
825 | 61b5e342 | Michael Hanselmann | - file-based storage has been implemented, which means that it is |
826 | 61b5e342 | Michael Hanselmann | possible to run the cluster without LVM and DRBD storage, for |
827 | 61b5e342 | Michael Hanselmann | example using a shared filesystem exported from shared storage (and |
828 | 61b5e342 | Michael Hanselmann | still have live migration) |

861 | bdc93557 | Iustin Pop | *(Released Wed, 24 Sep 2008)* |
862 | bdc93557 | Iustin Pop | |
863 | 61b5e342 | Michael Hanselmann | - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the |
864 | 61b5e342 | Michael Hanselmann | type of disk exported to fully virtualized instances. |
865 | 61b5e342 | Michael Hanselmann | - provide access to the serial console of HVM instances |
866 | 7faf5110 | Michael Hanselmann | - instance auto_balance flag, set by default. If turned off it will |
867 | 7faf5110 | Michael Hanselmann | avoid warnings on cluster verify if there is not enough memory to fail |
868 | 7faf5110 | Michael Hanselmann | over an instance. in the future it will prevent automatically failing |
869 | 7faf5110 | Michael Hanselmann | it over when we will support that. |
870 | 61b5e342 | Michael Hanselmann | - batcher tool for instance creation, see ``tools/README.batcher`` |
871 | 61b5e342 | Michael Hanselmann | - ``gnt-instance reinstall --select-os`` to interactively select a new |
872 | 61b5e342 | Michael Hanselmann | operating system when reinstalling an instance. |
873 | 61b5e342 | Michael Hanselmann | - when changing the memory amount on instance modify a check has been |
874 | 61b5e342 | Michael Hanselmann | added that the instance will be able to start. also warnings are |
875 | 61b5e342 | Michael Hanselmann | emitted if the instance will not be able to fail over, if auto_balance |
876 | 61b5e342 | Michael Hanselmann | is true. |
877 | 61b5e342 | Michael Hanselmann | - documentation fixes |
878 | 61b5e342 | Michael Hanselmann | - sync fields between ``gnt-instance list/modify/add/import`` |
879 | 61b5e342 | Michael Hanselmann | - fix a race condition in drbd when the sync speed was set after giving |
880 | 61b5e342 | Michael Hanselmann | the device a remote peer. |

886 | bdc93557 | Iustin Pop | *(Released Tue, 22 Jul 2008)* |
887 | bdc93557 | Iustin Pop | |
888 | 61b5e342 | Michael Hanselmann | - note: the allowed size and number of tags per object were reduced |
889 | 61b5e342 | Michael Hanselmann | - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups |
890 | 61b5e342 | Michael Hanselmann | - fixed twisted 8.x compatibility |

894 | 61b5e342 | Michael Hanselmann | - implement bulk node/instance query for RAPI |
895 | 61b5e342 | Michael Hanselmann | - add tags in node/instance listing (optional) |
896 | 61b5e342 | Michael Hanselmann | - experimental migration (and live migration) support, read the man page |
897 | 61b5e342 | Michael Hanselmann | for ``gnt-instance migrate`` |
898 | 61b5e342 | Michael Hanselmann | - the ``ganeti-watcher`` logs are now timestamped, and the watcher also |
899 | 61b5e342 | Michael Hanselmann | has some small improvements in handling its state file |
900 | 61b5e342 | Michael Hanselmann | |
901 | 10f31783 | Iustin Pop | |
902 | 10f31783 | Iustin Pop | Version 1.2.4 |
903 | 61b5e342 | Michael Hanselmann | ------------- |
904 | 61b5e342 | Michael Hanselmann | |
905 | bdc93557 | Iustin Pop | *(Released Fri, 13 Jun 2008)* |
906 | bdc93557 | Iustin Pop | |
907 | 61b5e342 | Michael Hanselmann | - Experimental readonly, REST-based remote API implementation; |
908 | 61b5e342 | Michael Hanselmann | automatically started on master node, TCP port 5080, if enabled by |
909 | 61b5e342 | Michael Hanselmann | ``--enable-rapi`` parameter to configure script. |
910 | 61b5e342 | Michael Hanselmann | - Instance allocator support. Add and import instance accept a |
911 | 61b5e342 | Michael Hanselmann | ``--iallocator`` parameter, and call that instance allocator to decide |
912 | 61b5e342 | Michael Hanselmann | which node to use for the instance. The iallocator document describes |
913 | 61b5e342 | Michael Hanselmann | what's expected from an allocator script. |
914 | 61b5e342 | Michael Hanselmann | - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the |
915 | 61b5e342 | Michael Hanselmann | ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a |
916 | 61b5e342 | Michael Hanselmann | node is lost there is still enough memory to fail over the instances |
917 | 61b5e342 | Michael Hanselmann | that reside on it. |
918 | 61b5e342 | Michael Hanselmann | - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to |
919 | 61b5e342 | Michael Hanselmann | ``gnt-cluster verify``, to check for site-specific compliance. All the |
920 | 61b5e342 | Michael Hanselmann | hooks will run, and their output, if any, will be displayed. Any |
921 | 61b5e342 | Michael Hanselmann | failing hook will make the verification return an error value. |
922 | 61b5e342 | Michael Hanselmann | - ``gnt-cluster verify`` now checks that its peers are reachable on the |
923 | 61b5e342 | Michael Hanselmann | primary and secondary interfaces |
924 | 61b5e342 | Michael Hanselmann | - ``gnt-node add`` now supports the ``--readd`` option, to readd a node |
925 | 61b5e342 | Michael Hanselmann | that is still declared as part of the cluster and has failed. |
926 | 61b5e342 | Michael Hanselmann | - ``gnt-* list`` commands now accept a new ``-o +field`` way of |
927 | 61b5e342 | Michael Hanselmann | specifying output fields, that just adds the chosen fields to the |
928 | 61b5e342 | Michael Hanselmann | default ones. |
929 | 61b5e342 | Michael Hanselmann | - ``gnt-backup`` now has a new ``remove`` command to delete an existing |
930 | 61b5e342 | Michael Hanselmann | export from the filesystem. |
931 | 61b5e342 | Michael Hanselmann | - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path |
932 | 61b5e342 | Michael Hanselmann | have been added. Using them you can enable/disable acpi and pae |
933 | 61b5e342 | Michael Hanselmann | support, and specify a path for a cd image to be exported to the |
934 | 61b5e342 | Michael Hanselmann | instance. These parameters as the name suggest only work on HVM |
935 | 61b5e342 | Michael Hanselmann | clusters. |
936 | 61b5e342 | Michael Hanselmann | - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and |
937 | 61b5e342 | Michael Hanselmann | PAE support will be set to the previously hardcoded values, but the |
938 | 61b5e342 | Michael Hanselmann | (previously hardcoded) path to the CDROM ISO image will be unset and |
939 | 61b5e342 | Michael Hanselmann | if required, needs to be set manually with ``gnt-instance modify`` |
940 | 61b5e342 | Michael Hanselmann | after the upgrade. |
941 | 61b5e342 | Michael Hanselmann | - The address to which an instance's VNC console is bound is now |
942 | 61b5e342 | Michael Hanselmann | selectable per-instance, rather than being cluster wide. Of course |
943 | 61b5e342 | Michael Hanselmann | this only applies to instances controlled via VNC, so currently just |
944 | 61b5e342 | Michael Hanselmann | applies to HVM clusters. |

955 | 61b5e342 | Michael Hanselmann | field will have) |
956 | 61b5e342 | Michael Hanselmann | - some more fixes for the mac export to hooks change |
